The Solar Occultation in the InfraRed (SOIR) instrument onboard the ESA Venus Express spacecraft, an infrared spectrometer sensitive from 2.2 to 4.3 μm, probed the atmosphere of Venus from June 2006 until December 2014. During this time, it performed more than 750 solar occultations of the Venus mesosphere and lower thermosphere. A new procedure has been developed for the estimation of the transmittance in order to decrease the number of rejected spectra, to check that the treated spectra are… Expand
An uppermost haze layer above 100 km found over Venus by the SOIR instrument onboard Venus Express

Martian dust storm impact on atmospheric H2O and D/H observed by ExoMars Trace Gas Orbiter
TLDR
The observed changes in H2O and HDO abundance occurred within a few days during the development of the dust storm, suggesting a fast impact of dust storms on the Martian atmosphere. Expand
The vertical distribution of ozone in Mars Years 34-35 from ExoMars TGO/NOMAD-UVIS observations
We present ~1.5 Mars Years (MY) of ozone vertical profiles, covering Ls = 163deg; in MY34 to Ls = 320deg; in MY35, a period which includes the 2018 global dust storm. Since April 2018, the Ultravio...
